Bioimpedance spectroscopy in haemodynamic analysis

Journal of Physics: Conference Series, 2010
Venous insufficiency is estimated to affect between 10% and 35% of the population in the US with symptoms ranging from mild discomfort to chronic ulceration which may reduce quality of life. Early diagnosis is the key to pre-emptive treatment. We have previously reported [5] an impedance technique for measurement of calf muscle pump function although ...

New bioimpedance analysis system: improved phenotyping with whole-body analysis [PDF]

European Journal of Clinical Nutrition, 2004
Bioimpedance analysis (BIA) is a potential field and clinical method for evaluating skeletal muscle mass (SM) and %fat. A new BIA system has 8-(two on each hand and foot) rather than 4-contact electrodes allowing for rapid 'whole-body' and regional body composition evaluation.This study evaluated the 50 kHz BC-418 8-contact electrode and TBF-310 4 ...

Deuterium oxide validation of bioimpedance total body water estimates in Hispanic adults

Frontiers in Nutrition, 2023
BackgroundTo date, body composition assessments in Hispanics, computed via bioimpedance devices, have primarily focused on body fat percent, fat mass, and fat-free mass instead of total body water (TBW).

Reproducibility analysis of bioimpedance-based self-developed live cell assays

Scientific Reports
Bioimpedance spectrum (BIS) measurements have a great future in in vitro experiments, meeting all the requirements for non-destructive and label-free methods. Nevertheless, a real basic research can provide the necessary milestones to achieve the success

External validation of BIA equations to estimate appendicular skeletal muscle mass in older adults: Importance of the bias analysis and derivation of correction factors to achieve agreement

Frontiers in Nutrition, 2022
There are several equations based on bioelectrical impedance analysis (BIA) to estimate with high precision appendicular skeletal muscle mass (ASM). However, most of the external validation studies have reported that these equations are inaccurate or ...

Effect of influenza-induced fever on human bioimpedance values [PDF]

, 2015
BACKGROUND AND AIMS: Bioelectrical impedance analysis (BIA) is a widely used technique to assess body composition and nutritional status. While bioelectrical values are affected by diverse variables, there has been little research on validation of BIA ...
